ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: This species seems to be the northern sister species of L. airlie ; males have a shorter, wider tip on the retrolateral tibial apophysis (fig. 139); females have a diamond­shaped epigynal midpiece (fig. 140) and widened spermathecae with very small anterior portions (fig. 141).

MALE: Total length 5.1. Abdominal dorsum with anterior pair of white spots small, median pair forming w­shaped stripe, not connected to posterior spot; anterior femora darkened, femora with distal, tibiae with proximal and distal dark rings. Palpal femur darkened throughout its length; retrolateral tibial apophysis basally triangular, tip long, directed dorsally (fig. 139); tegulum produced posteroventrally, extending to about one­third of tibial length; embolus narrow throughout its length (fig. 138).

FEMALE: Total length 7.2. Coloration as in male. Epigynal midpiece short, diamondshaped (fig. 140); spermathecae bipartite, posterior portion wide, globose, anterior portion small, bulbous, situated near midline (fig. 141).
